Monitoring & Alert

# === Monitoring Setup ===



# CrowdSec Metrics

# sudo cscli metrics

# sudo cscli decisions list

# sudo cscli alerts list --since 24h

#

# Prometheus metrics endpoint

# /etc/crowdsec/config.yaml

# prometheus:

#   enabled: true

#   level: full

#   listen_addr: 127.0.0.1

#   listen_port: 6060

#

# Grafana Dashboard for CrowdSec

# Import dashboard ID: 14541

เคล็ดลับ

• Hub: ติดตั้ง Scenarios จาก Hub ก่อน อย่าเขียนเอง ถ้ามีสำเร็จรูป
• Bouncer: ใช้ Firewall Bouncer สำหรับ Block ระดับ IP ดีที่สุด
• Console: ลงทะเบียน Console ดู Dashboard สถิติ Community Blocklist
• Whitelist: Whitelist IP ที่เชื่อถือได้ เช่น Office IP Monitoring
• Career: เริ่มจาก CompTIA Security+ แล้วเรียน CEH OSCP ตามลำดับ
